Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604450, here are decompositions:

67 + 31604383 = 31604450
79 + 31604371 = 31604450
103 + 31604347 = 31604450
109 + 31604341 = 31604450
139 + 31604311 = 31604450
151 + 31604299 = 31604450
223 + 31604227 = 31604450
313 + 31604137 = 31604450

Showing the first eight; more decompositions exist.
